Letters Patent No. 107 ,082, dated September 6,1870.

IMPROVEMENT. IN CARRIAGE-POLE COUPLING.

The Schedule referred to in these Letters Patent and. making part of thesame Be it known that I, QHARLES AMool-m, of Akron,- in the'county .ofSummit-and State of Ohio, have invented c'ertain new and usefulImprovements in Carriage-pole Coupling, of which the following is adescription.

Figure 1 is a side view of the carriage-pole. Figure'2 isa top view ofthe same.

Figure 3 is also a top view.

Figures 4 and 5 are detached sections.

Like. letters of reference. refer to like parts in the different views.

This invent-imrhas for its object the attachment of a double-tree to thepole of a carriage, so that itshall vibrate only to a certain requireddegree, thereby dispensing withthe check-straps or chains, now generallyused for that purpose, as set forth in the follow.- ing description.

In fig. 1, A represents a carriage-pole, of which B is the bound,whereby it is connected to the carriage, and

D, side braces,

E is the double-tree bar, and

F the single-tree, attached thereto, all of which are or 'ma-y beconstructed in the ordinary way.

The bar-E referred to is connected to the pole by means ofa bolt,a,andwhich is prevented from swinging or vibrating beyonda certain necessarydegree by means of a half circle, G, figs. 2 and 3, the ends of whichare secured to the under side of the bar E.

In the upper face of the semicircle is formed a deep, wide notch, H,fig. 4.

Said figure represents a front edge view of a detached half circle. Atop view of the same is shown in fig. 5,.in which H represents the notchreferred to.

I, figs. 2 and 3, isa reach or stay-strap, one end thereof being boltedto, the pole, whereas the other is secured by the bolt 0,.

It will be observed that the strap lies in the notch, hence, when thebar to which the half circle is attached shall be turned ineither-direction, obliquely to the direction of the pole, the shouldersof the notch will strike the strap, and thereby prevent the bar fromturning beyond a certain distance, to theex tent shown in fig. 2 in onedirection, and to that shown in fig. 3 when turned in the otherdirection.

By this means the double-tree or, single-tree, F, thereof are restrainedfrom falling sofar back as I0 strike the wheel of the carriage, inconsequence of an unequal strain being exerted upon the double-tree byan uneven draft of the team, or on turning around.

To accomplish this same purpose,there is ordinarily nseda strap orchain, attached to each end of'the bar E, whereas the other is attachedto the axle-tree.

Such straps soon wear out, or, if chains are used, they are heavy andnoisy, and both of which offer a lodgement for dust and mud, whereas,in,..my device for this purpose, it is more durable, ncatcr inappearance, and offers no lodgement for mud, 850.

It is also much stronger and safer, for, in the event of the breaking ofthe bolt a,-the semicircle will hold the team to the carriage, and,therefore, result in no serious injury.

What I claim as my improvement, and desire to secure by Letters Patent,is

The semicircle G, provided with a notch, H, when arranged in relation toand in combination with the double-tree E, p'ole A, and strap 1,substantially in the manner'as described, and for the purpose specificd.
